I understand your dilemna, I hope I can help you with this x3
Ok, so here's the thing:
Wings are pretty cool, obviously xD
And they represent something neat to: The ability to fly, to escape, to look things from above, etc.
And you can design them in any shape or form too!
Though I often feel many people, to put it bluntly, "just put/draw on some wings" because it's fun, or they can't think of anything else. Not much designing would be put into it.
And that's why I would advise
against it, but if you would make original-looking wings, or have some backstory as to why your character has wings to begin with, then it;s another story.
You could always have your character have some sort of steampunk or futuristic wings, which they can 'clip' on any time they wanted to. Be it because they designed it themselves and like to fly, maybe even because she wanted to catch birds?
Or maybe your character would be a special soldier in a flying unit, or something like so?
Just all kinds of ideas. But to just add wings because it might be cool, I think is a bad idea, and it's too often done. I'd like to always see backstory and see that some thought has been put into a character.
But that's just my opinion ^^
Hope my answer provided some help.
